Get the most out of your water-methanol injection kit with Speed Sauce™ 50/ 50 Water-Methanol Injection Fluid mix. It not only helps control detonation but can increase horsepower and torque with proper tuning. Secondly, our meth injection fluid is premixed and ready to use straight from the bottle. It won’t damage your vehicle’s paint if it spills or drips on the body of your car or truck. Speed Sauce can also be used as a water-methanol injection diesel fluid mix. In fact, when used in diesel applications, it provides both increased power and lowers exhaust gas temperatures. As a result, it allows for safer towing. Speed Sauce is perfect for turbocharged, supercharged, and high compression, naturally aspirated engines. It can deliver a 5 To 15 Percent power gain with proper tuning, but it also helps clean carbon deposits on the valves, pistons, and combustion chambers.
